This paper reports a 13-year-old female patient who presented oligodontia with absence of twelve permanent teeth. [austinpublishinggroup.com]

Mild attrition was present with mandibular molars (Figures 1(a), 1(b), and 1(c)). Radiographic Findings. [hindawi.com]

Population studies on the prevalence of hypodontia suggest that majority (more than 80%) will present with one or two congenitally missing teeth and only less than 1% will present with six or more missing teeth [10]. [omicsonline.org]

Similar findings have been observed in the present case report. [ncbi.nlm.nih.gov]

Anodontia of deciduous and permanent dentition in mandibular arch, as observed in the presented case, is rare. Hypodontia presents with varied manifestations. [contempclindent.org]

• Dentist

  With your dentist, you can determine the best treatment plan and enjoy a healthy set of teeth. [colgate.com]

  Therefore it is the responsibility of the dentist performing the oral habilitation to establish a diagnosis. [plus.rjl.se]

  Dentists while encountering with such patients with oligodontia, a detailed case history, physical examination to rule out syndromic form of oligodontia, and radiographs should be done to diagnose the case. [jioh.org]

  The restorative dentist must often act as a quarterback1 to coordinate multidisciplinary treatment approaches to patient care. [dentistrytoday.com]

  Therapeutic management of patients with hypo/oligodontia requires a multidisciplinary team including the pediatric dentist, orthodontist, a specialist in prosthodontics, and a maxillofacial surgeon. [rarediseases.org]

• Surgical Procedure

  procedures on the jaws, extraction of the preceding primary teeth, lack of necessary space imposed by a malformed jaw, and a genetically determined disproportion of tooth mass and jaw size. [ncbi.nlm.nih.gov]

  Developing teeth are affected by environmental factors such as multiagent chemotherapy, radiation therapy, fractures, surgical procedures on the jaws, extraction of the preceding primary teeth, and lack of necessary space imposed by malformed jaws.1,2 [ispub.com]

  Examples include jaw fractures, surgical procedures and extraction of the preceding deciduous tooth.[13] Treatment such as irradiation has been shown to have severe effects on developing teeth. [en.wikipedia.org]

• Developmental Delay

  Missing teeth are a common trait in modern populations and it is often encountered by dental practitioners.[1] Eruption of some teeth may be developmentally delayed by a number of years after the established time and others may show evidence of development [ncbi.nlm.nih.gov]

  All 3 children presented with ataxia and developmental delay, and were found to have microcephaly, short stature, oligodontia, strabismus, nystagmus, and congenital hip dislocation [23]. [wikigenes.org]

• Microdontia

  Generalized microdontia with spacing in the permanent dentition was appreciable (Figures 2(a), 2(b), and 2(c)). Radiographic Findings. [hindawi.com]

  Oligodontia is often related with conical shaped teeth, microdontia, delayed eruption of permanent teeth, an increased freeway space and retention of deciduous teeth. [ncbi.nlm.nih.gov]

• Delayed Dentition

  The following dental abnormalities were found: radiculomegaly, delayed dentition, oligodontia, root dilacerations (extension), and malocclusion [5]. [wikigenes.org]

• Tooth Loss

  One of the consequences may be an adult tooth intercepting with a baby tooth, causing premature loss or wrong positioning. [en.wikipedia.org]

• Eruptions

  At the insertion appointment, the complete incisal edge of the maxillary permanent right central incisor had erupted in the oral cavity, so further widening of the window created to accommodate the erupting tooth was done. [contempclindent.org]

  Orthodontic treatment should be aimed at improving the position of erupted teeth, guiding erupting permanent teeth and reducing the overbite. [10] Conclusion Every case of oligodontia should be reported so as to enhance the understanding of this rare [mjdrdypu.org]

  Variation in tooth morphology is also observed along with problems in tooth development, eruption and exfoliation. [orpha.net]

  A nonsense mutation in the b-catenin binding protein AXIN2 has recently been detected to cause familial oligodontia.[5,9] Oligodontia is associated with malformation of crowns, enamel hypoplasia, and failure of eruption. [ncbi.nlm.nih.gov]

  The teeth #43 and 44 had supra-erupted into the opposing edentulous area, further accentuating the upward cant of the occlusal plane in this area. [oralhealthgroup.com]

• Sweating

  Recent studies by Nordgarden (2001) have indicated that more than half of individuals with oligodontia also have symptoms from other organs of ectodermal origin such as low salivary secretion, decreased sweating capacity, sparse hair and dry skin, and [plus.rjl.se]

  Tooth agenesis is often associated with a group of conditions affecting the development or function of the teeth, hair, nails and sweat glands called ectodermal dysplasias. [rarediseases.org]

  Syndromic and non syndromic form of Oligodontia can be differentiated by conducting thorough physical examination of hairs, nails, sweat glands, eyes and to check for any congenital disorders. [ncbi.nlm.nih.gov]

• Fracture

  Missing teeth may be the result of numerous independent pathologic mechanisms that can affect the orderly formation of the dental lamina, failure of a tooth germ to develop at the optimal time, multi-agent chemotherapy, radiation therapy, fracture, surgical [ncbi.nlm.nih.gov]

  Developing teeth are affected by environmental factors such as multiagent chemotherapy, radiation therapy, fractures, surgical procedures on the jaws, extraction of the preceding primary teeth, and lack of necessary space imposed by malformed jaws.1,2 [ispub.com]

  Examples include jaw fractures, surgical procedures and extraction of the preceding deciduous tooth.[13] Treatment such as irradiation has been shown to have severe effects on developing teeth. [en.wikipedia.org]

• Suggestibility

  Brook and Bailit suggested that hypodontia is an example of a “quasicontinuous” trait with a threshold mechanism. [hindawi.com]

  This suggested that the extra amino acids may change the protein structure of MSX1 and affect its function. There are two possible explanations for this. [academic.oup.com]

  The multiplicity of hypodontia theories suggest that missing teeth are strongly influenced by genetic factor. [en.wikipedia.org]

  Further genotyping of the IVS2‐54A>G, IVS2‐109G>C, and IVS2‐41A>G mutations suggested that they can display polymorphic changes. [onlinelibrary.wiley.com]

  This may suggest incomplete penetrance of oligodontia in this family. However, the novel mutation was identified only in the proband, and his parents did not carry the mutation (Fig 2). [journals.plos.org]

• Neglect

  Oligodontia condition should not be neglected as it may result in various disturbances like abnormal occlusion, altered facial appearance which may cause psychological distress, difficulty in mastication and speech. [ncbi.nlm.nih.gov]

For the prosthetic treatment planning; patient’s age, expectation of treatment of the patient, the condition of retained primary teeth, the number of missing teeth should be taken into account. [pulsus.com]

The precise etiology of congenitally missing teeth is believed to originate from environmental or genetic factors during dental development. [dentistrytoday.com]

Although defects in certain genes have the highest incidence, etiological events in prenatal and postnatal periods have also been blamed for anomalies in tooth number, dimension, morphology, position, and structure [2]. [austinpublishinggroup.com]

It occurs with other dental anomalies such as microdontia, taurodontism, talon cusp, macrodontia, and gemination.[10] No definite etiologic relationship was found between oligodontia and systemic diseases or endocrine disturbances. [ncbi.nlm.nih.gov]

The diagnosis of hypodontia should be performed as early as possible in order to prevent aesthetic and functional problems in dentition. [ispub.com]

Developing malocclusion can be prevented if this condition is recognized and intervened in the earlier phase. Age of the patient plays a significant role in the management of the patient. [jdrr.org]

Early recognition is vital to provide adequate treatment and prevent squeal. Multidisciplinary referral or consultation is thus important in treatment planning to improve function and esthetics. [hindawi.com]
